What sorts of letters (or emails) do you think are most difficult

to write?

In my opinion, complaint letters are one of the toughest pieces of writing

because of the discomfort they may cause. Since I’m an easy-going and

conflict-averse person, I don’t usually complain when I should, whether it’s a

poor service experience or product. Hence, writing a formal letter of

complaint is even more difficult, especially when I have to carefully choose my

words and tones so it can be less critical and more constructive.

Discomfort (n): a feeling of worry or embarrassment

Conflict-averse (a): having a tendency to avoid conflicts

Constructive (a): having a useful and helpful effect rather than being negative

or with no purpose
